Dan Collins just wrote in, "I recently started my own cartoon blog. I've been a full time professional cartoonist since 1976."
Dan's work certainly fits into the Secret History of Comics - as he notes on his site, "Those cartoons have no doubt shown up in the inboxes of most of you at one time or another. Just look for the 'collins' at the bottom. If only I had a nickel every time they did."
I'm sure I've seen Dan's work that way too, but his blog is darned funny.
